I searched and didn't find anything. Could mean this is normal or it could mean that this iPad app doesn't search properly.

I've noticed that regardless of the settings on the AC, if I crack any of the windows the slightest amount, the AC pressure/blower increases a large amount. Is that normal? Or does it mean that some vents somewhere are clogged or closed? Also, if the AC is off when I close the doors and then turn the AC on, I can feel the pressure change in the cab.

think of it kinda like a furnace. you have to (with a furnace) have the same air coming in (RA return air) as you have air going out (SA supply air) does that make sense? more air coming in is always gonna be better...more efficient.

I've noticed a similar thing when I push the recirculate button on and off. I can feel the pressure increase when I turn the recirculate off. I assumed that the vent that the air goes out needs to be larger.

I dont get this cause in the manual it says for max AC put it on high and turn on the recirculate
